349 Business::OnlinePayment::InternetSecure is an implementation of
350 L<Business::OnlinePayment> that allows for processing online credit card
351 payments through InternetSecure.
353 See L<Business::OnlinePayment> for more information about the generic
354 Business::OnlinePayment interface.
358 Object creation is done via L<Business::OnlinePayment>; see its manpage for
359 details. The I<merchant_id> processor option is required, and corresponds
360 to the merchant ID assigned to you by InternetSecure.
364 (Other methods are also available -- see L<Business::OnlinePayment> for more
367 =head2 Before order submission
371 =item content( CONTENT )
373 Sets up the data prior to a transaction (overwriting any previous data by the
374 same occasion). CONTENT is an associative array (hash), containing some of
375 the following fields:
379 =item action (required)
381 What to do with the transaction. Only C<Normal Authorization> is supported
386 Transaction type, being one of the following:
394 =item - American Express
400 (This is actually ignored for the moment, and can be left blank or undefined.)
402 =item card_number (required)
404 Credit card number. Spaces are allowed, and will be automatically removed.
406 =item exp_date (required)
408 Credit card expiration date. Since L<Business::OnlinePayment> does not specify
409 any syntax, this module is rather lax regarding what it will accept. The
410 recommended syntax is I<YYYY-MM>, but forms such as I<MM/YYYY> or I<MMYY> are
415 Three- or four-digit verification code printed on the card. This can be left
416 blank or undefined, in which case no check will be performed. Whether or not a
417 transaction will be declined in case of a mismatch depends on the merchant
418 account configuration.
420 This number may be called Card Verification Value (CVV2), Card Validation
421 Code (CVC2) or Card Identification number (CID), depending on the card issuer.
425 A short description of the purchase. See L<"Products list syntax"> for
426 an alternate syntax that allows a list of products to be specified.
428 =item amount (usually required)
430 Total amount to be billed, excluding taxes if they are to be added separately
433 This field is required if B<description> is a string, but should be left
434 undefined if B<description> contains a list of products instead, as outlined
435 in L<"Products list syntax">.
439 Currency of all amounts for this order. This can currently be either
440 C<CAD> (default) or C<USD>.
444 Taxes to be added automatically to B<amount> by InternetSecure.
446 Available taxes are C<GST>, C<PST> and C<HST>. Multiple taxes can specified
447 by concatenating them with spaces, such as C<GST HST>.
449 =item name / company / address / city / state / zip / country / phone / email
451 Customer information. B<Country> should be a two-letter code taken from ISO
458 =head2 After order submission
462 =item receipt_number()
464 Receipt number of this transaction; this is actually a string, unique to all
465 InternetSecure transactions.
469 Sales order number of this transaction. This is a number, unique to each
470 merchant, which is incremented by 1 each time.
474 Universally Unique Identifier associated to this transaction. This is a
475 128-bit value returned as a 36-character string such as
476 C<f81d4fae-7dec-11d0-a765-00a0c91e6bf6>. See RFC 4122 for more details on
479 B<guid>() is provided as an alias to this method.
483 Date and time of the transaction. Format is C<YYYY/MM/DD hh:mm:ss>.
487 Total amount billed for this order, including taxes.
491 Cardholder's name. This is currently a mere copy of the B<name> field passed
496 Type of the credit card used for the submitted order, being one of the
505 =item - American Express
511 =item avs_response() / cvv2_response()
513 Results of the AVS and CVV2 checks. See the InternetSecure documentation for
514 the list of possible values.
526 =head2 Products list syntax
528 Optionally, the B<description> field of B<content()> can contain a reference
529 to an array of products, instead of a simple string. Each element of this
530 array represents a different product, and must be a reference to a hash with
531 the following fields:
537 Unit price of this product.
541 Ordered quantity of this product.
545 Internal code for this product.
549 Description of this product
553 Taxes that should be automatically added to this product. If specified, this
554 overrides the B<taxes> field passed to B<content()>.
558 When using a products list, the B<amount> field passed to B<content()> should
562 =head2 Character encoding
564 Since communication to/from InternetSecure is encoded with UTF-8, all Unicode
565 characters are theoretically available when submitting information via
566 B<submit()>. (Further restrictions may be imposed by InternetSecure itself.)
568 When using non-ASCII characters, all data provided to B<submit()> should either
569 be in the current native encoding (typically latin-1, unless it was modified
570 via the C<encoding> pragma), or be decoded via the C<Encode> module.
571 Conversely, all data returned after calling B<submit()> will be automatically
